Date: Sat, 29 Nov 2014 15:33:34 +0100 From: SF Markus Elfring <elfring@...rs.sourceforge.net> To: Jiri Kosina <jkosina@...e.cz>, linux-input@...r.kernel.org CC: LKML <linux-kernel@...r.kernel.org>, kernel-janitors@...r.kernel.org, Coccinelle <cocci@...teme.lip6.fr> Subject: [PATCH 1/1] HID: Wacom: Deletion of unnecessary checks before the function call "input_free_device" From: Markus Elfring <elfring@...rs.sourceforge.net> Date: Sat, 29 Nov 2014 15:16:01 +0100 The input_free_device() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.
